ABSTRACT
Existing methods of ridge terraces spacing calculation are characterized in the paper, as well as the way of spacing calculation by means of an erosion model – WinSEADS. The model has been verified by the results of three years’ field investigations which were carried out during the years 2000-2002 in the Agricultural Experimental Station in Puczniew on a 10% slope covered with medium loam. It was found that spacing calculated by existing methods differs considerably.

W pracy scharakteryzowano istniejące metody obliczania rozstawy tarasów grzbietowych oraz przedstawiono sposób obliczania rozstawy za pomocą modelu erozyjnego WinSEADS. Model zweryfikowano na podstawie trzyletnich badań terenowych nad spływem powierzchniowym, które wykonano w latach 2000-2002 w RZD Puczniew na stoku o średnim spadku 10% pokrytym gliną średnią. Stwierdzono, że wielkości rozstaw obliczone za pomocą istniejących metod i zastosowanego modelu są znacznie zróżnicowane.
